Filed: 1971-09-15
Abstract: 1401974 Sintered ferrous materials BRICO ENG LTD 30 Aug 1972 [15 Sept 1971] 42961/71 Headings C7A and C7D Ferrous material is made by sintering a mixture of iron-based powder and glass powder the material including iron in an amount of at least 50 wt per cent and glass in an amount of not more than 2 wt per cent, but not including lead except as a constituent of a glass. The iron may be present as a ferrous alloy, a low carbon steel or low alloy steel; other elements may be incorporated in the powder mixture. The glass may be a soda glass, a borate glass, a borosilicate glass or lead glass, the preferred minimum weight being 0.125%. Mixtures of the constituent powders with lubricants such as stearates of graphite are compressed and sintered at 1000‹-1300‹C under reducing atmospheres, e.g. dissociated ammonia or partially combusted propane/air mixtures. The sintered materials may then be case-hardened or quench-hardened and tempered at around 175‹C The presence of glass confers a lower porosity on the materials which are particularly suited for use as valve sears.

A shank lasting machine has grippers 20<SP>1</SP>, 21<SP>1</SP> and wipers 23 which can be moved from an out of the way position in which they are spaced perpendicularly from the last base to an operative position in which the grippers grip the lasting margin and the wipers are disposed adjacent the last periphery at approximately the height of the insole, there being provided a feeler which co-operates with the last base and which determines the movement of both the grippers and the wipers into the operative position. As described there are six grippers on each side of the last and each gripper 20<SP>1</SP>, 21<SP>1</SP> is formed on the ends of arms 20, 21 which move in a guide 24 and are operated by two pistons 36, 37 in a cylinder 35 so that each of the jaws moves towards the other jaw when the grippers are closed. Piston 36 and hence the jaw 21<SP>1</SP> can be locked in position by a piston rod 44 of a piston and cylinder 42, 43. The upper arm 21 of each gripper carries a forked member 22 which holds a wiper blade 23 e.g. of polytetrafluoroethylene which extends across the six grippers on each side of the last. The grippers are carried by individual slides 11 mounted in a guide 12 and are moved heightwise from the out of the way position to the operative position by a piston and cylinder unit 1, 2 acting through springs 9 so that each gripper moves heightwise until the jaw 20<SP>1</SP>, which acts as a feeler, contacts the last base, the grippers then being disposed in accordance with the contours of the last base. The grippers are then locked in this position by a piston and cylinder unit 29, 32 (Fig. 2 not shown) which clamps the slides 11 together in the guide 12. The guide 12 can slide heightwise in a carrier 61, a pin 50 on a lever 48 pivoted to the carrier at 49 engaging the guide 12 and causing heightwise movement when the lever 48 is pivoted by a piston and cylinder unit 51, 52 (Fig. 2 not shown).

Abstract: 1515229 Measuring non-linear distortion POSTA KISERLETI INTEZET 3 Nov 1976 [5 Nov 1975] 45691/76 Heading G1U In measuring the non-linearity of a nominally linear system, the response to a test signal is analyzed to provide an output representing a distribution function of the response which is both independent of the level of the response and which indicates the non-linearity. The Specification describes circuits for producing signals representing the amplitude distribution function (i.e. the probability that the response signal is less than or equal to a given threshold), the amplitude density distribution function (i.e. the probability that the response lies within the range between a threshold value x and x+#x, where #x is very small), and the density-moment function (i.e. the product of the means of the response signal and the threshold exceeding function, this being the probability of the response signal exceeding a given threshold. All these functions remain constant so long as the response signal shows no sign of distortion. The test signal is preferably stochastic e.g. Gaussian noise, but may also be a stationary signal providing the distribution functions thereof can be determined. The threshold level is always taken as the mean level of the response signal, and the function signal is averaged and compared to a reference level representing the mean value of an undistorted response, Figs. 10-16 (not shown).
